Hydreigon

one that stuck out to him immidiately was the Hydreigon suit, these pokemon were known for their brutallity and it didn't make a difference if you were a Magicarp or an Arceus, they would still challenge anyone in their way

. Ash's eyes lingered on the suit, his mind racing with the idea of embodying such a fearsome creature. The Hydreigon costume itself was a deep, midnight blue, with intricate scales etched into the fabric, giving it a textured, almost lifelike appearance. As he gazed at the suit, Ash felt an inexplicable sense of connection to it, as if he could already imagine himself wearing it, feeling the rush of adrenaline as he took to the skies, his three heads scanning the horizon for the next challenge.

he took it of the shelf and went towards the counter he saw that the shop was owned by a joung, but beautiful lady who said "Ah I see you have found a suit for yourself" she smiled as Ash put down the suit on the counter before saying "I don't know why but it fellt like I had a connection with this suit".

"Well that's a kink that my suits often have, when they feel the presents of someone that would be perfect as that pokemon, they pull them towards the suit" The lady's smile seemed to grow wider as she reached out to gently touch the Hydreigon suit, her fingers tracing the intricate scales etched into the fabric. Ash watched, fascinated, as her eyes sparkled with a knowing glint, as if she could see something in him that he couldn't see himself. "Yes, this suit has chosen you, and I think you'll find that it's a perfect fit," she said, her voice low and soothing. She glanced up at Ash, her gaze meeting his, and he felt a shiver run down his spine as she asked, "Would you like to try it on?"

Ash nodded as he took back the suit, as the Lady said " in the back there are changing rooms so you would be undesturbed" Ash nodded as he was about to go there "oh yeah when your transformation is done, I may have another thing that you will like" Ash was confused at that sentence but decided to put that into the back of his mind for now.

As Ash turned to head towards the changing rooms, the soft rustle of the fabric of the Hydreigon suit filled the air, and he couldn't help but feel a thrill of excitement. He walked down a narrow corridor, the walls of which were adorned with framed photographs of people wearing various Pokémon costumes, their faces beaming with joy. The air was thick with the scent of fabric dye and the faint hint of something else, something almost medicinal, which Ash had noticed when he first entered the shop.

The corridor eventually led him to a small, dimly lit changing room, the door of which was slightly ajar.

When he opened the Door he saw it wasn't much, just a bench, a Chair and a mirror, he then put the Suit down before taking of his cloths and when he took of his underwear he was ready to start his new life, at the back of the suit was an opening for him to climb in, first he put in his legs and feet into the stubby legs of the suit where he was taken of gard as they completly fit into the little space without damaging the suit, then he put his arms and hands into what were a Hydreigon's second and third head but also worked as hands for the species, then lastly he put his head into the suit, , before he laid down on his stomach waiting for the suit to perform it's.

the Suit started with his legs and feet first his legs shrunk out of existence as his feet extended in lenght while his toes fused together into 3 clawed paws as they filled the suit giving him the feet of a hydreigon, next his stomach balloned outwards to fill the stomach of a hydreigon, meanwhile his organs rearanged themself to fit such a powerful Dark Dragon such a he was going to be, next his arms extended a bit to fit the suit while when they were in place his hands fused together before forming his new heads, whose maw were filled with razor sharp fangs and on top of them were two eyes to complete his new hand/heads, next he fellt his neck expanding both in lenght and width as it filled the neck of the suit and when his head arrived at it's destination, he fellt his head slowly morph into that of a Hydreigon as his Eyes moved to the sides with with his iris and pupil turning a beautful deap purple while his scalera turned pitch black, lastly his jaws expanded outward into the proud muzzle of a hydreigon filled with Razor sharp fangs and nosedrills on the top end of his muzzle ending the changes for his head and neck but not the changes to his body since he still didn't have his tail and wings, but that would change shortly after that since he fellt 6 bonestructures extending out from his shoulder blades and another one from his tailbone filling the tail and wings of the suit, as the cotten in them was replaced by, Nerves, vains and flesh enabling him to move them at his will, lastly the suit fused with his body completing his transformation and he fellt the wind flying against his black fur and his scales and it fellt unbelieveble to his.

As the transformation completed, Ash felt an overwhelming sense of exhilaration and freedom. He stretched his new body, feeling the powerful muscles beneath his scales ripple and flex. His three heads swiveled, taking in the cramped changing room from different angles, the eyes adjusting to the dim light. The air was thick with the scent of his own body, a mix of sweat and ozone that was both familiar and yet completely alien.

He experimentally flapped his wings, feeling the wind rush past his face as the delicate membranes vibrated with the motion. The sound was almost musical, a soft whooshing that seemed to harmonize with the beating of his heart.

used Flamethrower on his old cloths not wanting to change back from this beautiful and powerful Hydreigon into a pitiful weak human being and burned them to a crisp.

As the flames consumed his old clothes, Ash felt a sense of liberation wash over him. The smell of burning fabric and the faint hint of smoke filled the air, mingling with the scent of his own scales and fur. He watched, mesmerized, as the flames danced and flickered, casting eerie shadows on the walls of the changing room. The sound of crackling fabric and the soft whoosh of the flames seemed to grow louder, more intense, as if echoing the pounding of his heart.

with that out of the way he heard someone cought from behind him and when he looked back he saw the shopowner on his side "Well at least you took that out of here is what, I wanted to show you" she said as she took out a potion which was a mix of red and Black " this will turn you into a complete monster that only wants to battle Strong opponents and defeat them in the most brutal way, the only exception to that are those that you call friends and mates you make along the way, for those you will only have complete loyalty."

As the shopowner held out the potion, Ash's three heads instinctively leaned in, their eyes fixed on the swirling mixture of red and black. The air seemed to vibrate with anticipation, and Ash could feel his heart pounding in his chest, his scales quivering with excitement. The shopowner's voice was low and husky, her words dripping with an otherworldly allure as she continued, "This potion will unlock your true potential, unleash the beast within. Are you prepared to take the leap, to surrender to your primal instincts?" Ash's jaws parted, revealing rows of razor-sharp teeth, as he let out a low, rumbling growl, the sound echoing off the walls of the changing room.

Ash nodded and took the Potion with one head and opened it with the other head before raising the potion to his big mouth and gulping down every last bit of it, and when the last drop of it landed inside his muzzle, he fellt his primal instincts well up in him, making him want to tear apart every pokemon from small to big, apart from what he would come to call Friends and Mates, for those he would only have complete Loyalty, Meanwhile his Dragon and Dark Powers rose to a level that could rival a Mega Rayquaza, as Hades, which was what he started to call himself since Ash was to weak and pathetic for such a glory as himself felt pure Dark and Dragon energie running through his Vains and he loved every bit of it.
